What minimum software version is required on a device for SWIM to upgrade the software?
A. The software version requirements vary among classes of devices. Cisco IOS-based devices must run at least Software Release 10.3. Cisco IOS Software Releases before 10.3 do not provide Management Information Base (MIB) or Command-Line Interface (CLI) interfaces required by SWIM to manage the devices. With Catalyst (Layer 2) switches, the minimum software requirement is Cisco IOS Software Release 2.1 on Supervisor. SWIM requires the minimum Cisco IOS Software Release 3.2(4) on Cisco 760 Series Integrated Services Digital Network (ISDN) routers and Cisco IOS Software Release 4.0(1) on 770 Series ISDN routers.
